By default, Flux doesn't do nudity at all, but of course it did not take long for people to attempt to de-censor it. It still doesn't do nudity anywhere near as well as SDXL/Pony, but it does it.
That being said, the nipples are varying degrees of successful in impersonating real ones, sexual organs only exist in female variety, and even those are not what you have come to expect.
On the other hand, the rest is often sensational.

Update: It's getting better at anatomy.
